DAKOTA HOOD FOR BABY OARRIAGES November 6, 1929.

My present invention has for object to provide a simple and highly efficent folding hood for baby carriages and while intended for general use,is especially well adapted for use in connection with my folding babycarriage disclosed and broadly claimed in a oopending application, filedDecember 12, 1928, under Serial No. 325,411 of which the presentapplication is a division.

To the above end, generally stated, the invention consists of the noveldevices anolcombinations of devices hereinafter described and defined inthe claims. 7

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a right side elevation of the improved hood mounted on thebody of a folding baby carriage;

Fig. 2 is a front elevation of the same with a portion of the babycarriage sectioned on the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary view of the hood in longitudinal verticalsection, on an enlarged scale;

Fig. 4 is a fragmentary detail view of the intermediate section of thehood removed from the central bow;

Fig. 5 is a fragmentary detail View with some parts sectioned on theline 55 of Fig. 1, on an enlarged scale; and

Fig. 6 is a perspective view of one of the bow supports and attachedbows.

The improved hood 7 is made from flexible material mounted, as shown, onthree metallic tubular bows 8 and attached thereto by flexible cores 9of any suitable material, for instance manila rope. The hood 7 isattached to the cores 9 by being folded therearound and secured theretoby stitches or other fastening means 10. These cores 9 are mounted inthe bows 8 by threading the same endwise therein and longitudinal slots11 are formed in the inner sides of said bows through which the hood 7extends, see Fig. 3.

The end portions of the bows 8 are flattened at 12 and attached to bowsupports in the form of bearing plates 13 pivotally mounted on drawbolts 14 carried by brackets 15 rigid- Divided and this applicationfiled. Serial No. 405,115. I

ly secured to the sides of the upper frame member 16 of a folding babycarriage body 17, at the longitudinal centers thereof. By reference toFig. 6, it will be noted that the intermediate how 8 is rigidly securedto the bearing plates 13 by a pair of bolts 18 and that the outer bows 8are pivoted thereto by single bolts 19 whereby said outer bows may befoldedonto said intermediate bow. The brackets 15, as shown, in Fig. 5,are U-shape in cross section and the inner side members thereof arerolled more than half-way around the frame member 16 and rigidly securedthereto by rivets. V

The bearing plates 13 extend between the side members of the brackets 15in contact with the inner faces of the outer side members of saidbrackets and the bolts 14 extend through bores in said outer sidemembers and are intermediately supported therefrom. To permit theapplication of the bolts 14 to the outer side members of the brackets15, large passageways 20 are formed in the inner side members of saidbrackets. Spring washers 21 are applied to the bolts 14 and bear againstthe inner faces of the bearing plates 13. Also applied to the bolts 14between their heads Said the washers 21 are short spacing sleeves Theouter side members of brackets 15 are outwardly bulged to substantiallythe same shape as the washers 21 but in reverse order, as indicated at23, so as to insure good frictional contact between said side plates andthe bearing plates 13. Hand nuts 24 are applied to the bolts 14 and bytightening the same, the bearing plates 13 will be frictionally heldbetween the outer side members of the brackets 15 and washers 21 to holdthe hood 7 where set.

The lower portions of the hood 7 meanchored to the bolts 14 by providingsaid hood with grommets 25 and mounting the same on the spacing sleeves22. These spacing sleeves 22 are of such length as to prevent thegrommets 25 from being clamped between the heads vof the bolts 14 andthe washers 21 which'would prevent the same from turning duringdifferent adjustments of the hood 7 about the axis of the bolts 14.

To hold the outer bows 8 spread in respect to the intermediate bow-8 andthereby hold the hood 7 stretched taut between said bows there isprovided at each side of the hood 7 a toggle lever 26. The ends of thetoggle levers 26 are pivoted to the outer bows 8 and a U-shape member 27is attached to each intermediate pivot of the toggle levers 26. SaidU-shape members 27 are so arranged that the members of the toggle levers26 engage the transverse portions of said members during thestraightening movements of said levers after their intermediate pivotshave passed beyond dead centers to lock the toggle levers 26 with thehood 7 open, (see Fig. 1).

The customary buckle-equipped crossstrap 28 is provided to prevent ababy from falling out ofthe baby carriage and which strap is releasablysecured to apertured lips 29 formed with the inner rolled portions ofthe brackets 15.

By flattening the ends of the tubular bows 8 a two-ply stock is producedwhich greatly strengthens said bows where the bolts l8l9 extendtherethrough. When flattening the ends of the bows 8, the stock isrolled or turned into the tubular ends of said bows, and against theinternal surfaces thereof so as not to obstruct the openings therein. Toapply the hood 7to the bows 8, the cores 9 are first attached theretoand thereafter said cores are inserted endwise into the bows 8 and thehood 7 edgewise into the slots 11.

The toggle levers 36 are attached to the bows 8 before the hood 7 isapplied thereto by spreading the bows 8 at their slots 11 where theholes are formed therein for the rivets which pivotally connect the armsof said toggle levers to the bows 8. In applying the rivets to the bows8 and toggle levers 36, said rivets are inserted through the holesprovided therefore in said bows from the inside thereof so that thepre-formed heads on rivets are within the bows thus eliminating alldanger of the rivets pulling out as a result of poorly formed heads. Therivets, after the toggle levers 36 are applied thereto, are upset toform heads on their outer ends and which heads are exposed to view sothat the same may be readily inspected for defects.

What I claim is: l

1. A hood of the class described having a plurality of bows, a pair ofpivot plates to which the bows are attached, a pair of U- shapedbrackets having on one of their side members means for attaching thesame to a supporting body, clamping bolts pivotally connecting the pivotplates to the other side members of the bracket, and washers on thebolts, said bolts being operable to frictionally clamp the pivot platesbetween the washer and side members of the brackets in which the boltsare mounted, spacers between the heads of the bolts and the washers, andgrommets in the hood through which the spacers loosely extend withfreedom to permit said grommets to turn thereon.

2. A hood of the class described having a plurality of bows, a pair ofpivot plates to which the bows are attached, a pair of laterally spacedU-shaped members, the inner side members of which are relatively wideand shaped to form seats that are more than semi-circles incross-section, and applicable to a body member that is round incrosssection, and clamping bolts pivotally connecting the pivot platesto the outer members of the brackets, said seats having apertured lipsfor attaching a cross strap to the brackets.

In testimony whereof I aflix my signature. J
